Excessive pressure and oil blowing back into air intake.

Hi Folks,

I have been having a problem where my engine runs away at high speeds (2.0 L Series Diesel).

A friend suggested adding some sort of tank as I have here and taking it for a run, it did not run away and felt a lot better but as you can see I have excessive oil recirculating.

I am keen to get to the bottom of why this is happening - I have an idea but need to ask here before I start taking action I need to ask here first.
Here's the result of my test run, I got up to 90.

Hi All,
Finally fixed this today.

It was excessive blow by via piston 1 - basically when I had my runaway the engine did seize only on that Single Piston - there was a big chip ontop of the piston at the side, also the piston was scored.

I replaced the piston - four complete sets of rings, Honed all of the Bores - Ground all of the valves in again (Only No1 was bad).

oh, and the tapping noise that troubled me was a cam follower - I pulled all of these apart to clean them and No6 blew its check valve out (this was where the noise was coming from).

Bought a 3 hole Head Gasket (It already had a 3 hole one installed) too.

Threw it all back together and its sounding like it should now

The trickiest bit was getting the Cam Belt Cover off, also locking the Flywheel was a bit of a problem at first but I eventually found the hole for the pin - locked that off as well as the fuel pump.

I saved myself an absolute fortune - I think the whole lot cost me about £250 in parts.

** Replaced all of the Big End Bearing Shells too.
I went to a Land Rover Dealer for a quote at first for the parts and they almost wanted £1k

Good result!

well done fella
